Describe the bug

The documentation for blmove indicates that it should work similarly to lmove in that a source destination and left/right directions are to be used (twice).

To reproduce

127.0.0.1:6379> RPUSH mylist "one"
(integer) 1
127.0.0.1:6379> RPUSH mylist "two"
(integer) 2
127.0.0.1:6379> RPUSH myslist "three"
(integer) 1
127.0.0.1:6379> BLMOVE mylist eldos LEFT RIGHT
(error) ERR wrong number of arguments for 'blmove' command

Expected behavior

Same as lmove, which works.

Additional information

Validated with redis 6.2.4, and 6.2.5.
